AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BOISE ID
929 AM MDT SAT MAY 7 2011

.DISCUSSION...WE UPDATED FOR CURRENT COVERAGE OF SHOWERS IN OUR
CWA...AS OF 15Z SHOWERS WERE MOSTLY SOUTH AND EAST OF A SUN VALLEY
TO MOUNTAIN HOME LINE.  AIR MASS WILL BECOME UNSTABLE ENOUGH THIS
AFTERNOON FOR ISOLATED THUNDERSTORMS OVER MOST ZONES...EXCEPTIONS
HARNEY COUNTY AND THE STILL SNOW-COVERED TERRAIN OF CENTRAL IDAHO.
REMAINDER OF FORECASTS UNCHANGED.  12Z BOI RAOB SHOWED TEMPERATURES
SIMILAR TO YESTERDAY FROM THE SURFACE TO 600 MB...CURRENT FORECAST
LOOKS GOOD.

&&

.AVIATION...WIDESPREAD RAIN SHOWERS WITH MVFR CEILINGS WILL CONTINUE
IN IDAHO EAST OF A WEAK COLD FRONT WHICH EXTENDED ALONG A SUN-KMUO
LINE AT 15Z. SFC WINDS HAVE SHIFTED TO LIGHT NW BEHIND THE FRONT
WITH SCT-BKN CLOUDS.  CLOUD BASES WILL BE NEAR 8000 FEET MSL AND
OBSCURE MTN TOPS BUT VFR CONDITIONS WILL PREVAIL THIS AFTERNOON
BEHIND THE FRONT IN VALLEY LOCATION OF SOUTHWESTERN IDAHO AND
EASTERN OREGON.  MORE RAIN AND SNOW SHOWERS WILL DEVELOP ACROSS THE
AREA TONIGHT AS AN UPPER LEVEL LOW MOVES OVER THE AREA.

&&

.HYDROLOGY...UNREGULATED RIVERS ARE RISING ACROSS SOUTHWESTERN IDAHO
AND SOUTHEASTERN OREGON THIS MORNING...BUT NONE ARE FORECAST TO GO
ABOVE FLOOD STAGE WITHIN THE NEXT SEVERAL DAYS. RAINFALL AMOUNTS
RANGED FROM 0.10 TO 0.25 INCHES ACROSS THE OWHYEE AND BRUNEAU RIVER
BASINS LAST NIGHT AND WILL NOT BE ENOUGH TO DRIVE THESE RIVERS ABOVE
FLOOD STAGE.  RAINFALL AMOUNTS OF 0.50 TO 1.00 INCHES FELL IN THE
HEADWATERS OF THE PAYETTE AND BOISE RIVER BASINS LAST NIGHT...BUT
COLDER TEMPERATURES WILL SLOW SNOW MELT AND RESERVOIR REGULATION
WILL PREVENT FLOODING ON THESE RIVERS FOR NOW.

&&

.PREV DISCUSSION...
SHORT TERM...TODAY THROUGH SUNDAY...COLD UPPER LOW NEAR THE QUEEN
CHARLOTTE ISLANDS BY LATER THIS MORNING WILL FILL BY ABOUT 100M AT
H5 AS IT DIGS TO OVER WA EARLY SUNDAY MORNING. AHEAD OF THE LOW
CENTER A SHORTWAVE TROUGH HAD ITS BACK EDGE FROM HELLS CANYON TO THE
LEE SLOPES OF THE STEENS AS OF 3 AM. PRECIPITATION AMOUNTS SINCE 6
PM HAVE RANGED FROM A TENTH OF AN INCH OR SO AT IDAHO CITY-ONTARIO-
LITTLE MCCOY CREEK TO LESS THAN 0.05 INCHES /WITH DRY PARTS/ ACROSS
MOST OF THE IDAHO TREASURE AND MAGIC VALLEYS. THE WAVE SHOULD EXIT
THE BOISE AREA BY 9 AM WHICH WILL BRING THE BREAK IN OREGON EAST TO
OVER THE IDAHO VALLEYS THIS AFTERNOON. THIS WILL LEAD TO INSTABILITY
THIS AFTERNOON FROM AROUND BAKER THROUGH BOISE TO TWIN FALLS. SO IN
OREGON AND THE VALLEYS LOOK FOR SCATTERED SHOWERS AND ISOLATED
THUNDERSTORMS UNTIL LATER TONIGHT WHEN THE NEXT ROUND OF RAIN /AND
MTN SNOW/ MOVES INTO THE AREA AS THE UPPER LOW MOVES CLOSER TO SW
IDAHO. TERRAIN ENHANCEMENT IN IDAHO WILL KEEP MORE NUMEROUS/
WIDESPREAD PRECIP GOING TODAY. AREA OF HIGH MOISTURE SOUTH OF THE
UPPER LOW WILL BE DRAWN INTO IT AND LEAD TO AN AREA OF BANDED
SHOWERS OVER FAR SE OREGON AND FAR SW IDAHO MOUNTAINS LATE TONIGHT-
EARLY SUNDAY...WHICH THEN LIFTS NE ACROSS THE REST OF SW IDAHO
SUNDAY AFTERNOON/EVENING. A DECENT AMOUNT OF PRECIPITATION IS
FORECAST ACROSS THE SOUTHERN RIVERS AND STREAMS /BASINS SUCH AS
DONNER UND BLITZEN...OWYHEE...UPPER MALHEUR...BRUNEAU...SALMON
FALLS/ BUT COLD AIR IS ALSO COMING IN TO CHANGE THE PRECIPITATION TO
SNOW. SO AN INCREASE IN FLOW AND AN ADDITION TO THE ALREADY 150-200+
PERCENT OF NORMAL SNOWPACK IS ON TAP. LIGHT WINDS WILL PICK UP
SUNDAY AS THE SURFACE HIGH BUILDS IN BEHIND THE BANDED
PRECIPITATION. COOLING IS STILL ON TRACK ESPECIALLY SUNDAY AND NOW
POPS ARE HIGHER AGAIN AS THE NAM/GFS/EC ARE IN GOOD AGREEMENT THAT
AT LEAST THE IDAHO PORTION WILL HAVE PRECIPITATION THROUGH MID-
AFTERNOON VALLEYS AND THROUGH THE DAY IN THE MOUNTAINS.

LONG TERM...SUNDAY NIGHT THROUGH FRIDAY...UPPER LOW CENTER IS
POSITIONED OVER THE GREAT BASIN ON MONDAY. INSTABILITY AND WRAP-
AROUND MOISTURE WILL KEEP WIDESPREAD PRECIPITATION ACROSS SE OREGON
AND SW IDAHO. FOR TUESDAY SE OREGON ZONES DRY OUT WITH PRECIPITATION
LINGERING OVER SW ID MTNS AND CENTRAL IDAHO VALLEYS. HIGH AMPLITUDE
RIDGE DEVELOPS OVER THE INTERMOUNTAIN WEST WEDNESDAY SHIFTING TO THE
EAST ON THURSDAY BRINGING DRIER CONDITIONS AND ABOVE NORMAL
TEMPERATURES. GOOD MODEL AGREEMENT ON PATTERN EVOLUTION THROUGH
TUESDAY. BEYOND TUESDAY...MODELS CONTINUE TO SHOW DEVELOPMENT OF
DEEP CUTOFF LOW OFF THE WEST COAST WITH RESULTING SW FLOW OVER THE
INTERMOUNTAIN WEST LATE NEXT WEEK. THIS WOULD KEEP AREA MILD AND
POTENTIALLY MOIST DEPENDING ON THE TRACK OF THE UPPER LOW.
